Your 1224's look a lot better than mine. I keep thinking that they could be upgraded into decent amps. I have three working amps a dud that have bee collecting dust for a few years. How do they sound?
Those 602s sure are pretty! Don't think I've ever seen a pair before. Thanks for all the cool pix!
Very cool pix indeed. Thanks for posting them!
Now if you'll just send your complete address, date of birth, mother's maiden name, social security number, computer passwords, and location of the rock under which you keep your secret house key, I will send you an entirely valid certified check and have my chauffeur come and pick up the lot. ;-)

All Picts are very nice. I love that Altec Green on the first photo.
I have snabbed quite a few off the web my self over the years.

Very interesting to see all this Altec gear and the places it is in. I couldnt imagine what one of the very early Altec or "best" Altec systems would sound like in a cinema, I bet it was astounding.... I wish there was more info, or a catalog of the places Altecs have been, or a registry of some sort...
OK tube gurus, edumacate me.Quote:

And, there's no visible "flash" on the glass because it's a thoriated filament type, and the getters aren't flashed with an RF pulse like many of the more common small signal and power tubes are?

Those two 845s are manufactured by "United Electronics Company" out of my home state, New Jersey, perhaps Newark as I recall. That tube is also called the " United 945".
Notice the UNIQUE inverted glass nipple at the very top of the tube, which serves to hold the top of the plate structure steady.
United Electronics just put ALTEC's logo on their manufactured tubes, very common back then. Cool to see today.
I have a similarly structured United 945 on my desk that was made 43rd week of 1943, and it actually has silver flashing, but no cylindrical pill box. Likely that pill box serves as a getter, I'm also just guessing. Those tubes are most probably 1952 manufacture, maybe 19th week.

You made me look closer, now i'm noticing the machine screw and nut that clamps the internal assembly to the glass "plug" at the base. It's easy to see how that package was inserted in the envelope before evacuation and sealing. Even new, those must have been a fairly costly tube, labor intensive assembly. Neat stuff!
During WW2, a lot of women were employed making tubes for the war effort. Except, when they were undergoing their menstrual cycles, in which case, they didn't build tubes !! There was something transmitted through their skin, that goofed up the tubes. I learned this from Bob Fulton, speaker designer, owner of Fulton Musical Industries ( 1925-1988 ). R.I.P. Bob !!Quote:

On eBay this past month, two such 845 tubes , ( branded as United Electronics 845 ) sold for $1,100 each. SO, there is likely some validity to it being Western Electric made, at THAT price for one "untested" tube from "an estate".
The people of the Far East seem to know all of this, judging from their bid frequency and amounts bid.

i have one of those. not in that good of shape though
I used to search for images on blogs to make my presentations more interesting, it took a lot of time and was less effective than when I found a website with ideas, for example, angel wings logo . I was impressed with these graphic elements, as there is a large selection of them and I can find what I really need!
